370 基本 例題 13 複利計算と等比数列 毎年度初めにα円ずつ積み立てると, n 年度末には元利合計はいくらになる か。 年利率を、1年ごとの複利で計算せよ。 CHART & THINKING nの問題 n=1,2,3, ・・・で調べてn化 (一般化) 中央大 p.365 基本事項3基本11 「1年ごとの複利で計算」とは、1年ごとに利息を元金に繰り入れて利息を計算することを いいこの計算方法を複利計算という。 なお,1年度末の元利合計は、次のように計算される。 (元利合計)=(元金)+(元金)×(年利率)=(元金)×(1+年利率) この例題をn=3として考えてみると,各年度初めに積み立てるα円について,それぞれ 別々に元利合計を計算し、 最後に総計を求めることになる。 a 積み立て ← 1年度末 a(1+r) a 積み立て ← 2年度末 3年度末 a(1+r)² a(1+r)³ a(1+r) a(1+r)² a 積み立て a(1+r) 上の図から、3年度末には α(1+r)+α(1+r)2+α(1+r) 円になる。 これをもとに, n 年度末の元利合計を和の形で表そう。 解答 各年度初めの元金は,1年ごとに利息がついて(1+r)倍と ← α円は なる。 D にα ( 1 + r) 円, よって,第1年度初めのα円は第n 年度末には α(1+r)"円, 第2年度初めのα円は第n年度末にはα(1+r)1円 2年後にα(1+r)2円, となる。ゆえに、求める元利合計Sは,これらすべての和で S=a(1+r)"+a(1+r)"-1++a(1+r) (F) これは, 初項 α(1+r), 公比 1+r, 項数nの等比数列の和で あるから, 求める元利合計は (1+r)-1 S= a(1+r){(1+r)"-1}__a(1+r){(1+r)"−1} (円) r PRACTICE 128 ......n …… 年後にα(1+r)" 円になる。 α(1+r) を初項, α(1+r)" を末項とする。 Jei
